I want to conduct a survery on my website where users can select answers of a question. I am confused how to normalize the database. I am writing here the table definitions:

tblUsers

UserID, Username, PhoneNumber

tblQuestions

QuestionID, Question_Description

tblChoices

ChoiceID, QuestionID, Choice_Description

* A question has more than one choices, users can select multiple answers.

Now I want to know how to save users options against a question. I think that there is missing table(s) which are confusing for me. If anyone can normalize this database, I will be thankfull.

Just add one table

tblSurvey

AnswerID, UserID, QuestionID, ChoiceID
 
 
This way a user can have as many answers as you want, thus you can write a constraint to limit the number or asnwers for each users

Thanx michael. Will you be kind enough to write a query here showing results of the survery from tblSurvery table for each user (by question and its choice) so that I can print out the survery. This time I am confused how to Join tables. Thanx in advance.

Actually scratch the Question ID column from the tblSurvey, did not see you had it in there.....
After that just do a simple join between the tables....
